The Design of 35kV High Voltage Power Distribution CabinetAbnormal Temperature Alarm System
High voltage power distribution cabinet often appears some accidents due to poor contact and other reasons. In view of this phenomenon, an alarm scheme is proposed for the high voltage power distribution cabinet, which is infrared thermal imaging technology based on ARM embedded system. The design selects 32 bits RISC microprocessor S3C2440 as the main control device, selecting μC/OS-Ⅱ operating system which is portable and scalable as the software operating platform, realizing remote transmission of image information by Ethernet. The design can implement the alarm of the high voltage power distribution cabinet which is abnormal temperature, finding faults in time, avoiding accidents. The scheme has the advantages of low power consumption and high reliability, and has good engineering significance and broad prospects for development.
